JavaScript - Replace Space With Underscore

in the div class "done" it reads 13/34
i want to compare these to numbers like this

if (13 < 34){do something()}
else {return false;}

so i am trying to get each number by it self to compare with.

var did=m[1].getElementsByClassName("done")[1].innerText.replace(/\/.*/,"").value;
this line returns 13 correctly.

var need=m[1].getElementsByClassName("done")[1].innerText.replace(? ,"").value;
this ? the info that i need to get for the other number.
i know how to do it if it were a letter but can find the correct way being that it is a / instead.

Thx

I found a regular expression that will strip my string of every html tag...

var stripped = htmlStr.replace(/(<([^>]+)>)/ig,"");

Well, I also want it to strip every thing between parentheses, square brackets, and replace " &# 160;" with a space.

It would be really cool if you could explain how to do this as well, because the stuff in the above code after "replace" confuses me. I have no idea how that's working.

Hi, I need function for replacing one string with some html tag (for example <div>something</div>) in web page. Tricky is that in this replacing I must ignore all text between <a> and </a>. It's look easy but I am not good in javascript.

Code:

  dropDownPart.innerHTML = tmpInnerHTML;

how does this tmpInnerHTML gets filled :

Code:

for (var i = 0; i < arr.length ; i++)
{
        var arr1 = arr[i].split('|');
        id_tezaver = arr1[0];                  
         term = arr1[1]   
        // if  arr1[1] contains ',   then ewerything after that disapears inside term,
        // like "bird's eyes"  becomes  "bird"
        // how to handle that   ? 
       
        // bad example how I get to verify that the stuff is complete inside array
        // term = arr1[1].replace(/'/i, /oo/); 

}

I have a javascript that takes information from a form and recompiles that information into a readable shift report. The problem I am having is with returns in the textareas. I tried:

Code:

theReport = theReport.replace("
","<br>"

but that space puts the rest of the var on a different line and screws with the results. How can I replace a return with <br>?

I know how the replace method works, but I can't for the life of me figure out exactly what this replace function is doing... Can someone shed somelight for me? the g I *think* is a flag for global replacement...

Code:

replace(/\s/g, " ");

I know that *something* is being replaced by a non-blank space, but what?

Hi all,

I have this code:
Code:

<input type="hidden" value="update_cart" name="ca">
<input type="hidden" value="2" name="numcart">
<input type="submit" name="submit" value="Update Cart" class="inpSubmit">

I'd like to replace this:
Code:

<input type="submit" name="submit" value="Update Cart" class="inpSubmit">

with this:
Code:

<button>blabla<button>

How can I do?
I know something about unobtrusive javascript but I don't know how to do it.

Thank you very much

Building a javascript shopping cart for an assignment. First time using Javascript so ignore the ****ness of it please

Anyway basically I need to replace the qty of an item in an array if the item has already been added to the array. if it hasn't then it adds the normal values to the array.

So I assume atm that I have to run an if statement when the function

Code:

function readInput(prd, qty, prc){

is called that checks in the array before pushing the new values into the array if array contains product name then var id = productarrayID+1 then replace that with the new quantity read in by the form.

Quantity in my array is after the product name so I assume productarrayID+1 would give me the qty id variable.

So heres the steps, be they correct:

1) get product name from HTML.
2) check if array contains product name.
3) continue with adding to array if product name doesn't exist in array.
4) if array contains product name retrieve id of product name within array.
5) + 1 to the ID to the product name thus giving me the ID for the quantity.
6) run some array.replace with the new id and replace with the quantity.

Just wondering if thats a year or no to how that would run. Il post my HTML code but please dont post solutions I would prefer to write the code myself but just checking if the step-by-step process would work thankyou.

Building a shopping cart, at the moment I have 1 variable array. My JS gets values from hidden inputs when add to shopping cart is clicked. The JS then pushes them all into the array in order.

I've managed to get the js code to replace innerHTML and add the array to the HTML to show the products, quantity and totals in a table. However its only showing the last product, price, and total in the array in the table. I need to get it to do this:

Product: Quantity: Total:
Product1 1 1
Product2 2 2
Product3 3 3

So basically I think I need to have my 3 for statements then plus 2 to each i instead of i++ to print out the products but that still doesn't solve my problem with printing every product in a vertical list, same with quantity and same with total.

Heres the code

Code:

var cart= new Array();

function readInput(){
				
		var prd=document.test.prd.value;
		
		var prc=document.test.prc.value;
		
		var qty=document.test.amount.value;
		var total= prc * qty;
		
		cart.push( prd )
		cart.push( qty )
		cart.push( total );
		
		var lenp=cart.length;
		
		for(var i = 0; i<lenp-2; i++ ) {
		document.getElementById("product").innerHTML = cart[i];
		}
		for(var i = 0; i<lenp-1; i++ ) {
		document.getElementById("qty").innerHTML = cart[i];
		}
		for(var i = 0; i<lenp; i++ ) {
		document.getElementById("total").innerHTML = cart[i];
		}

}

This functions should replace uppercase chars with bold and lowercase with italic.


It should return: Big Bad wolf, Small red ball - HI

Unfortunately there's something wrong with it and I'm getting this: Big Bad wolf, Small red ball - HI

Not sure what 's wrong.

Code:

function replaceIt(mystr){
	
	var str = "Big Bad wolf, Small red ball - HI";
	var tmppicstr = "";
	var tregex = /[^a-zA-Z\s-,\/]/;
	var lccheck = /[:lower:]/;
	var ltcheck = /[a-z]/i;
	
	if(tregex.test(str) == true){
		return str;
	} else {
		
		for(var x=0;x<=str.length;x++){
			
			var tmpchar = str.substring(x, (x+1));
			if(ltcheck.test(tmpchar) == true){
				
				if(lccheck.test(tmpchar) != true){
					tmppicstr = tmppicstr + "<b>" + tmpchar + "</b>";
				}else{
					tmppicstr = tmppicstr + "<i>" + tmpchar + "</i>";
				}
				
			}
			if(tmpchar == " ") tmppicstr = tmppicstr + (" &nbsp; ");
			if(tmpchar == ",") tmppicstr = tmppicstr + ("<b>" + tmpchar  + "</b>");
			if(tmpchar == "-") tmppicstr = tmppicstr + ("<i>" + tmpchar  + "</i>");
			if(tmpchar == "/") tmppicstr = tmppicstr + ("<b class='sl'>" + tmpchar  + "</b>"");

		}
	}
	return tmppicstr;
}
